        Structural formula:

        Synthetic rout:

        From the reaction of lauryl alcohol (12 alcohol) and hydrobromic acid: the lauryl alcohol was added into enamel glass reaction pot, stirring and cooling, slowly adding sulfuric acid, stirring for 1 h. Then adding hydrobromic acid, the temperature is gradually raised to 90 ℃ 95 ℃, stirring reaction is 8 h, the reaction is finished, and the temperature is reduced to 30 ℃ for 8 h. The acid layer is separated, and the oil layer is adjusted by dilute alkali liquid to separate the lye solution. The product was washed with 50% ethanol and distilled by vacuum distillation. The product was obtained with a yield of more than 90%.
